dbo:abstract
  • HD 29559 is a solitary star in the southern constellation Caelum. It has an apparent magnitude of 6.40, placing it near the max naked eye visibility. The star is situated at a distance 408 light years based on parallax measurements but is receding with a heliocentric radial velocity of 24.2 km/s. HD 29559 has a stellar classification of A5 IV-V — a luminosity class intermediate between a main sequence star and subgiant. It has alternatively been classified as A3 Vs:, indicating that it is an A-type main-sequence star with sharp (narrow) absorption lines due to slow rotation. However, there is uncertainty behind the class. It has 2.19 times the mass of the Sun and a slightly enlarged diamter of 3.17 R☉. It radiates at 35 times the luminosity of the Sun from its photosphere at an effective temperature of 7,852 K, which gives it a white hue. Contrary to the second classification, HD 29559 spins rapidly with a projected rotational velocity of 176 km/s and has a solar metallicity. It is estimated to be 719 million years old, having completed 85.9% of its main sequence lifetime. (en)
  • HD 29559 är en ensam stjärna i den mellersta delen av stjärnbilden Gravstickeln. Den har en skenbar magnitud av ca 6,41 och är mycket svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 8,0 mas, beräknas den befinna sig på ett avstånd på ca 407 ljusår (ca 125 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 24 km/s. (sv)
